For most people who experience hearing loss, the condition comes on gradually over a period of years. In rare cases, an abrupt loss of hearing occurs with little or no warning. This condition, known as sudden sensorineural hearing loss (SSHL), is defined as a hearing reduction of 30 dB or greater over three contiguous frequencies, occurring over a period of 72 hours or less.<\/p>\r\n\r\n\r\n\r\n
Ninety percent of cases result in unilateral (single-sided) hearing loss, which may be accompanied by dizziness or tinnitus.<\/p>\r\n\r\n\r\n\r\n
The severity of the hearing loss varies. Some patients recover completely and without medical intervention in just a few days. Others find their symptoms improve gradually over a couple of weeks. Fifteen percent of those who experience sudden deafness will have hearing loss that worsens over time.<\/p>\r\n\r\n\r\n\r\n
